Great visibility, but light fabric makes it vulnerable to everyday nicks and scrapes
Polaris RBS Radar high-visibility backpack
6 10

With the days still winter-short, there isn't much choice but to commute in the dark for most. Even with lights, anything to aid the visibility to other road users is a plus. A fluorescent bag is a wise addition, as it increases one's visible area. The Polaris RBS Radar Pack is a simple but effective offering.

The bag is a relatively basic backpack. A full length zip around three-quarters of the bag allows it to open like a clam shell, for easy access and packing of its 25l capacity. Inside the main void there is nothing more complicated than a netted laptop pouch. The place to stash and separate small items is the secondary clamshell on front of the main one. This area features three divisions and a zipped, phone sized pouch.

Twenty-five litres is enough for most short commutes, to fit your lunch and other bits and bobs. You'd struggle to get a full change of clothes in it but I imagine most looking for a bag like this have already considered the sizing for their needs.

A cushioned back with removable foam that gives the bag form makes the backpack comfortable to wear (you can put a hydration pack in place of the foam). There isn't much to the straps but for the capacity of the bag it shouldn't cause much problem. It isn't a terribly technical design but I found it suitable and inoffensive on my back for my short ride to work. Braces clip around the waist, with pocket and fluorescent material for a small amount of extra front visibility.

The primary selling point for the bag - high visibility - is well ticked. The majority of the bag is fluorescent lime-yellow colour, with reflective printed chevrons and text - creating a almost glowing bulge on the wearer's back. If you don't think this is enough, or your bike doesn't have a rear light, there is a clear pouch at the base of the bag to place a light; it's accessed from the main pocket.

While the light weight if the bag is great in terms of loading, the thin material makes it feel cheap. I also had issues with the durability of the single lined skin, with a small gash appearing after only a few uses with nothing of odd shape. It could have been a unfortunate clip somewhere but the material didn't inspire confidence in its longevity.


The suggested retail price of £49.99 is perhaps a little expensive for what is quite a simple bag. It can be found for around £40 however and when you consider that the popular bag covers by Respro cost £20 and upwards (the closest comparison I could find), the price is a bit more competitive.

It comes down to whether you want to add eflectivity to a bag that you already know and works for you or want a simple backpack too. If the latter than the RBS Radar is a good bag, with the option of adding more visibility through lighting (the lit Respro covers cost about £40).

On the average head down arse up commuter the bulk of the hi-viz and reflectives on this bag, just like ever other similar backpack or bag cover will be of more use to passing aircraft passengers who want to spot cyclists than following car drivers.

What seems like a nice chunk of flouro-fabric (useless under street lights at night but never mind) and reflective trim when stood upright becomes a small, very small, flash of colour when you are actually riding along. Particularly to a car driver who is looking up at the bag from a position often lower than a riders 'arris.

If the designers are serious they need to make the base of such bags as reflective and brightly coloured as the body of the bag.

imo. ime. ymmv.
